UNITED STATES PATENT OFFICE.

STEAM-BOILER HOUSE.

SPECIFICATION forming part of Letters Patent No. 408,172, dated July 30, 1889.

Application filed October 3, 1888. Serial No. 287,084. (No model.)

To all whom it may concern:

Be it known that I, JOHN L. GILL, Jr., a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in the Art of Constructing Steam-Boiler Houses; and I do hereby declare the following to be a su fliciently full, clear, and exact description thereof as to enable others skilled in the art to make and use the said invention.

This invention relates to the arrangement of batteries of steam-boilers or steam-generators in plants requiring large aggregations of steam-generating capacity, and has for its object economy of space, economy of labor in attendance, and the facility of access for cleaning and repairs.

To effect these several desiderata this invention consists of a combination in one structure of a fuel receiving and storage apparatus, a fuel-distributing apparatus, and an ash collecting and discharging apparatus, With building, furnace, and boiler constructions adapted thereto, as hereinafter described, and as shown in the accompanying drawings, by means of Which the most simple plan of handling, storing, anddistributing of fuel and the collecting and removal of ashes from the furnaces is effected, the expenses of labor in operating the plant are reduced to a minimum, a perfect and regular supply of fuel to each boiler-furnace is secured, and perfect cleanliness of the building is obtained.

Figure 1 shows a transverse vertical section of a three-story boiler-house; Fig. 2, a length- Wise vertical section of the same.

The same reference marks indicate like parts in both iigures.

` A', A2, A3, and A4 represent boilers or steamgenerators resting on the ground floor, and may be either Water-tube boilers or returntubulars; B', B2, B3, and B4, steam-generators in similar settings on the second iioor.

C and C2 are nests of economizers on the third Hoor.

D is a chimney, Which may be made of metal throughout or masonry throughout, but preferably in brick or masonry, extending above the roof-line of the building and there contracted and supplemented by a cylindrical metallic stack D.

D is the extension of the chimney above the roof, Which may be made of metal or masonry.

D2 are vertical divisions of the iiues E', E2, E3, E4, and F', F2, F3, and F4, Which are desirable but not essential.

D3 is a partition-Wall, which extends centrally from the bottom of the chimney to a point above the level of the second-story battery of boilers, or, in case the economizers are used, to a point above the level of the upper part of the economizers C' and C2.

E', E2, E3, and Et are fiues leading' laterally from the furnaces A', A2, A3, and A4 to the basc of the stack D, which is expanded at the point of the intersection of the flues F', F2, F3, and F", so that at this point the chimney is .equal in cross-sectional area of the several flues E', D2, E3, and E4, and F', F2, F2, and F1.

G G are lateral flues for conducting theV G', when in a vertical position, and allow the products `of combustion to directly ascend the stack D, or,when in a cross position, close the stack above the opening G', so as to turn the gases into the flues G G.

As above described, the apparatus for draftdistribution is the subject of claims in a distinct application for Letters Patent, serially numbered 287 ,085, filed on the 3d day of Oct-ober, 1888, and is here shown and described to afford a clearer understanding of the fuel storage and distribution and ash ycollecting and discharging apparatus andl the furnace construction adapted thereto and the relation of these par ts to the spaces and passage-Ways for affording access to the several port-ions of the plant. 4

J and J2 are the longitudinal walls of t-he boiler-house.

K is the ground-Hoor.

K is the second-story floor.

K2, the third-story floor. L is the roof of the building.

M is a coal dump or hopper under the railroad track outside of the building, Where coal is received by gravity from the cars.

TOO

M is a chute to carry the coal to the boot' veyer M11 M11, which is used to convey the coal to either of the longitudinal conveyers V V through the hoppers M8 or M0.

M12 and M12 are storage-bins for receiving coal and storing same till needed, and should be made large enough to hold at least one weeks supply of coal; M14 and M15, hopperbottoms of the coal-bins, through which the coal feeds by gravity to the pipes M10 and M17; M16 and M17, pipes for conveying coal by gravity to the hoppers of the automatic stokers.

M12 are gates by which the supply of coal t0 the Stokers is controlled; M20 and M21, hoppers of the automatic stokers; N and N2, furnaces of the automatic stokers, which may have common iiat grates; but inclined reciprocating grates are preferably used, the furnace shown being for the Well-known NV. P. Roney stoker.

N3 and N4 are troughs through which the spiral conveyers O, Fig. 2, or the endlesschain conveyers O O2 pass while removing the ashes that fall into them.

O, Fig. 2, is a spiral conveyer, which may be used instead of the chain conveyers O2 O2.

O O are the paddles or scoops on the endless-chain conveyers O2.

O2 O2 are the endless-chain conveyers used to remove the ashes from themseveral furnaces in which they are made, and to discharge them directly into the ash-bins W (through the chute V) or into the boot OB of the elevator O4. These endless chains O2 are returned over the furnaces when the furnaces project far enough in front of the boilers, as shown at boiler A2; otherwise they are returned over the boilers, as shown at boiler B2.

O2 is the lower wheel of the endless-chain elevator O4.

O4 is the endless-chain elevator used to raise the ashes from the boot O8 and discharge them into the bins V through the chute O7.

O5 are the buckets on the elevator-chain.

O0 is the upper driving-wheel of the elevator O4.

O7 is a chute through which the ashes pass into the bins WV from the elevator O4.

P P are intermediate floors placed at the level of the hoppers M20 and M21, affording access at a convenient level to the hoppers M20 and M21, and also to the upper portion of the boiler-fronts, and leaving spaces or passage-ways Q at the level of the furnace-l ioors. Q Q are passage-ways used' by the firemen in taking care of the grates and ash-conveyers.

R R are passage-ways under the iiues E', E2, E2, and E1, and F', F2, F3, and F4 at the rear of the boilers, affording easy access to the rear end of the boiler-settings and to the tubes of perposed fuel-storage bins and elevators, and V horizontal conveyers arranged to raise and distribute fuel to said bins, combined with hoppers located at a lower level and pipes provided with adjustable gates for distributing fuel by gravitation and regulating the supply thereof from said storage bins and hoppers into the several furnaces, substantially as set forth and shown.

2. The described boiler-plant, having fuelstorage bins provided with hoppers and pipes having adjustable gates therein for distributing fuel to the several furnace-hoppers inclosed within a building having floors affording access to the furnace-hoppers located intermediately between the boiler-supporting iioors and covering air-conduits to the ashpits, substantially as set forth.

3. In a boiler-plant, the combination of the furnace, provided with feeding-hoppers, with the described fuel elevating and distributing apparatus and storage-bins located above the furnace-levels, with tubes leading to the vseveral furnace-hoppers, and ash-conveyers arranged to continuously remove ashes from the several furnaces, substantially as set forth and described.

4. The combination of self feeding and stoking furnaces arranged in series horizontally, with conveyers to continuously remove the ashes from the ash-pits of the several furnaces, floors located intermediately between the supporting-floors and ceilings of the boilerrooms, arranged to afford access to the fuelfeeding hoppers of the furnaces and to form conduits for air to the ash-pits excluding ashdust from the furnace and boiler rooms, substantially as set forth.

5. In a boiler-plant, the combination of the described fuel elevating and distributing apparatus with one or more series of boilers arranged in a line and provided with a horizontally operating ash conveying mechanism, which continuously removes the ashes from the entire line of furnaces at the same level,

and an ash elevating and discharging` appaelevator for removing the ashes from the oonratus, arranged substantially as and for the Veyer to an ash-storing bin, substantially as 1o purpose set forth. set forth and` shown.
